摘要
考虑一般具有时间依赖时滞和连续分布时滞的N-种群同期Lotka-Volterra型系统.通过使用Liapunov函数方法得到了关于正周期解的存在性和全局渐近稳定性的充分条件,这些条件改进和推广了最近被Wang,Chen,Lu[2]和Ahlip,King[4]得到的相应结果.
In this paper a general n-species periodic Lotka-Volterra type system with distributed delay and time dependent delay is considered. Sufficient conditions for the existence and global asymptotic stability of positive periodic solutions is established by applying the method of Liapunov functions. These conditions improve and extend the recent ones obtained by Wang, Chen and Lu [2] and Ahlip and King [4].
